ABSTRACT:
In an electronic camera having a photographic objective lens, a blocking member is disposed in the path of a propagation of a bundle of light rays from an object. The blocking member is adapted to prevent the bundle of rays from impinging on an image pickup device except during a photographic operation. The blocking member is retractable from the path to permit the bundle of rays to be incident on the image pickup device. A photoelectric conversion circuit includes photoelectric conversion elements arranged in the form of a matrix. A charge control circuit controls the amount of charges to be stored in the photoelectric conversion circuit while the blocking member is completely retracted from the path. An image processing circuit produces an image signal based on the amount of stored charges.
